DYNO RUN ON THE E28 M535I WITH M5 ENGINE

[BM WORLD 1286]

better results than last time . after tweaking the afm pointer after some porsche mecanic by previous owner had fiddle with it ....

wish these socalledexperts would leave things alone ...

so we reset the fuel quality switch in the ECU back to zero .

then played with the spring tension on the afm till we got a better result .

tried it after this run a little richer but it only returned a richer AFR and no extra power , so the only thing we an do is play with the chip in the ECU and dial in a bit more timming and fuel at the top end .

pics of previous atempt this year and todays results .

also i need to look into sheilding the airintake from a hot air under the bonnet .

Well done Brent. Power curve has a nearly identical profile to the 540.

Now for a 1/4 mile time. Decent engine in a light weight car. Should be pretty quick.
